获取此错误java.lang.IndexOutOfBoundsException:索引487超出长度487的界限

我正试图使用下面的程序打印下拉列表，但它抛出了

索引outofboundsexception

然而，它正在打印大约70-80个列表，然后抛出一个错误。如何打印控制台中的所有值

public void searchText() {
        searchTxtField.sendKeys("m31");
        ArrayList <WebElement> list = (ArrayList<WebElement>) driver.findElements(By.xpath("//*[@class='_3BEcOp']//div"));
        System.out.println(list.size());

        for(int i=0 ; i<=list.size() ; i++) {
            System.out.println(list.get(i).getText());
        }
    }

public void searchText（）{
searchTxtField.sendKeys（“m31”）；
ArrayList=（ArrayList）driver.findElements（By.xpath（“//*[@class=”[u 3BEcOp']///div”）；
System.out.println（list.size（））；
list.forEach（element->System.out.println（element.getText（））；
}

使用上述代码。这将在任何情况下解决IndexOutOfBoundsException异常。只需检查给定列表是否为空，否则在每个代码中使用forEach

只需迭代到

（列表长度）-1

从

中删除
=
我应该是
i
而不是
我使用list.forEach（element->System.out.println（element.getText（））；而不是for循环。注意索引的范围是从
0
到
size-1
。替换
ii@vishalgupta这是因为您正在尝试获取列表容器中不存在的索引数据。As索引从0开始到list.size（）-1。您正在尝试获取不存在的list.size（）。
